I really don't care
Research is important to the writing of history beause it's fact and evidence. Bias is a very important thing to avoid in the writing of history because history tends to repeat itself, knowing history is a great way to avoid future mistakes but bias can make learning history difficult because it's not entirely true.
befrore there wasnt much bias now there is
Social Bias, often occurs in history and is a problem with primary sources, as they sometimes reflect the interests of one particular social group rather than society as a whole , and this may give us a distorted picture of things.
I know nothing about fixed bias,So I try this web to know but this web address fail to answer my question.What_is_fixed_bias_circuitthis is a fake web it can't help anyoneSudip
It is a bias of a fixed voltage supplied by a separate low-power bias supply. Early radios used a 9 v tapped bias battery. In some amplifiers fixed bias can be dispensed with and the bias voltage is derived from one of the currents in the circuit.

low input impedance
the advantage of self bias circuit will be stable for greater range of amplitude signal than the fixed biased amplifier circuit the disadvantage is it only partially effective and therefore is only used where moderate changes in ambient temperature are expected
Various FET biasing circuits are as follows: 1. Fixed bias 2. Self bias 3. Potential divider bias 4. Current-Source bias
Advantages: 1) This is a simple circuit which uses very few components 2) The operating point can be selected anywhere in the active region of the characteristics by simply changing the value of Rb.Thus,it provides maximum flexibility in the design. Disadvantages: 1) Thermal stability is not provided in the circuit.Thus Q-point is not maintained. Ic = β Ib + Ico Ic = β Ib 2) Since Ib is already fixed,Ic depends on β which changes unit to unit and shifts the Q-point.Thus the stability is very poor.
